• Perform weld joint preparation and cleanliness to prevent contamination, oxidation, or weld metal embrittlement.

• Maintain consistent weld quality despite wind, weather, humidity, temperature, and restricted access.

• Follow all site-specific safety rules and permits (hot work, confined space, elevated work, etc.).

• Identify hazards such as pressure boundaries, stored energy, heat stress, or oxygen-deficient areas.

• Properly set up: Fire resistant welding screens or hooch’s, fire watches, and spark containment measures. following the site's safety requirements

• Use all PPE including appropriate welding clothing, respirators, fall protection, and eye/hand protection.

• Produce welds meeting acceptance criteria for VT, RT, UT, PT, or MT as applicable.

• Read and follow WPS, P&IDs, ISO drawings, weld maps, and material specs.

• Maintain traceability (heat numbers, filler control, joint verification) according to the Welding Program and Quality Control Department expectations.

• Self-inspect welds before QC notification.

• Report weld defects, equipment issues, or deviations immediately.

• Meet or exceed daily weld count and productivity targets set by supervisors.

• Adapt to changing job priorities such as emergent repairs or shutdown critical path work.

• Work effectively with fitters, riggers, pipe crews, inspectors, and engineering when needed.

• Manage welding consumables efficiently, minimize rework, and maintain equipment readiness.

• Accurately documented weld numbers, joint completion, and material verification.

• Participate in daily toolbox talks, safety briefings, and quality meetings.

• Communicate challenges early (access, fit-up issues, equipment damage, consumable needs).

• Support weld sequencing and field installation planning.

Figure 1. 6GR Restricted Jig Dimensions

Optional test, in accordance with the site needs (by Welding Superintendent request):

Every welder qualification test must first pass visual testing per ASME Section IX paragraph QW-302.4 and meet the requirements of ASME Section IX QW-194 in addition to the following:

• No linear indications allowed.

• No visible porosity allowed.

• No incomplete fusion (cold lap) allowed.

• No tungsten craters or arc strikes/arc blow/arc marks allowed.

• No slag allowed.

• No incomplete penetration allowed.

• 1/32 in. (0.8 mm) root concavity (suck back) allowed, except for classification EX010 electrodes where zero root concavity is permitted.

• If the coupon thickness (T) is less than or equal to 1/4" (6.4 mm), the maximum internal weld reinforcement shall not exceed 1/16” (1.6 mm); above 1/4" (6.4 mm) coupon thickness (T), the maximum internal weld reinforcement shall not exceed 3/32” (2.5 mm).

• External reinforcement shall not exceed 1/8 in.

• Complete fusion of weld metal and base metal.

• Undercut shall not exceed 1/32 in., (0.8 mm). No blending with a file or post weld grinding is allowed, only wire brushing.

• Backing strip (if used) shall be fused for its entire length. Welders will not be able to back weld the coupon after the backing strip is removed.

Note: Welder shall not move the pedestal around after the weld is tacked into the 6G/6GR jig, until completion of the weld.

Reporting

• Reports directly to the assigned Welding Foreman or Welding General Foreman and performs work in accordance with approved drawings, welding procedures, and work instructions.

• Collaborates daily with welding leads, pipe fitters, and other craft personnel to support proper sequencing, fit-up readiness, and efficient workflow.

• Coordinates with Quality Control and inspection personnel to facilitate required inspections, address weld acceptance issues, and support corrective actions or rework as directed.

• Works in alignment with Safety personnel to ensure compliance with site safety requirements, and safe work practices.

• Communicates equipment issues, material concerns, access constraints, and quality or safety observations promptly through the established supervision chain.

• Supports construction progress by responding to field direction and maintaining effective working relationships across all interfacing disciplines.

Physical Requirements

• Employees will be required to adhere to large amounts of standing, walking, bending, squatting, sitting and lifting.

• Will talk and hear to communicate.

• Will use arms and hands to signal, grab, hold, turn, push, and pull objects, materials, controls and tools.
